fication on/off
The "cooling with dehumidification" function
is only available when the engine is running.
The air inside the vehicle is cooled and dehu-
midified according to the temperature selec-
ted. This prevents the windows from misting
up. G
Risk of accident
If the "cooling with air dehumidification"
function is deactivated, the air inside the
vehicle will not be cooled (during warm
weather) or dehumidified. The windows
could mist up more quickly. This may pre-
vent you from observing the traffic condi-
tions, thereby causing an accident. H
Environmental note
The cooling system uses the refrigerant
R134A. This refrigerant does not damage
the earth's ozone layer.
Condensation may drip from the underside of
the vehicle when Thermatic is in cooling
mode. X
To activate: press the9button.
The indicator lamp in the 9button lights
up.
X To deactivate: press the9button.
The indicator lamp in the 9button goes
out. The cooling with air dehumidification
function has a delayed switch-off feature. Controlling the air conditioning auto-
matically
In automatic mode, the set temperature is
maintained automatically at a constant level.
The system automatically regulates the tem-
perature of the dispensed air, the airflow and
the air distribution.
The automatic air conditioning will achieve
optimal operation if "cooling with air dehu-
midification" is also activated. If necessary,
cooling with air dehumidification can be deac-
tivated. Cont
